cLooK BANK.

Application filed-February 23, 1923. Serial No. 620,592.

To all whom it may concern.

Be it known that we, VVILLIAM D. PEN- NINGTON and JOHN R. PENNINGTON, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Clock Banks, of which the following is a full, clear, concise, and exact description, reference being. had to the accompanying drawings, forming a part of this specification.

Our invention relates to clock banks, and particularly to such as have coin controlled winding mechanism.

One of the objects of the invention is to provide a simple, practical and advantageous construction of clock bank.

Another object of the invention is to arrange for the effective prevention of the winding of the clock unless a coin is deposited.

, Another object of the invention is to prevent tampering with the mechanism by unauthorized persons.

In the accompanying drawings Fig. 1 is a rear elevation of a clock bank with the back cover removed embodying our presentinvention;

Fig. 2 is a side elevation of the same with a portion of the bank casing broken away for convenience of illustration;

Figs. 3 and 4 are views of details of construction;

Fig. 5 is a view similar to Fig. 1 of a modified form of device. 7

Referring to the drawings, we show a bank 1 having a coin aperture'2 inits back wall. A coin holder 3 is arranged to receive the coin when the same is inserted in the aperture. The coin holder 3 may be in the form of a rotary member mounted on a rotary shaft 4, as shown in the drawings. The coin holder 3 may be in the form ofa rotary member mountedon a rotary shaft 4, as shown in the drawings. The coin holder.3 has three spaces 5, 6 and 7, each adapted to hold a coin. Said spacesare of different sizes, however, so as to hold coins ofdifferent dimensions. Space 5 is to hold a dime, space 6 a nickel, and space 7 to hold aquarter. A stem 8 is provided to permit turning of the'holder 3 so that when a coin is inserted in the coin aperture said holder 3 may be turned to swing the coin around in a circular path inside of the annular lip 8.

A d ice is provided for astuation y the coin when moved by the member 3. The device shown ispreferably in the form of a dog 10 mounted on a spindle 11 and having an end 12 arranged to project into the path of a coin traveling in the coin chute or slide formed by the member 8. The dog 10 is also provided with an arm 13 having a hook or abutment 14 and a second arm 15, the use of which arms will be later explained.

The main spring of'the clock is shown at 16, being operated. by a windingstem 17.

For preventing the winding of. the clock Without the use of a coin, Y nism' which will now be described. This involves an auxiliary spring 18 mounted in a rotary drum 19, the spring 18 being also mounted on and having one end secured to the key winding stem 17 whereas the other end is secured to the rotary drum 19. The latter has onejor more projections 20 to engage the hook or abutment 14onthe arm 13, and so prevent rotation ofthe drum 19 we employ mechaby means of spring 18. The Winding shaft 17 has a pin 22 to engage the other arm 15 of the dog 10. Y r Y 7 When the mechanism is in the position shown in Fig. 1, the spring 18 iswound, having been wound by an operation winding the clock. It is held against rotation, however, by abutment 14 on arm 13. When a coin is inserted in the aperture 2 and into one of the recesses in the holder '3, said coin when moved by'holder 3 will strike against projecting end '12fand thereby swing pawl 10 so as to withdraw arm 13 froinpin 14 and permit the spring 18 to unwind. drum 19. This will permit the spring 18 to be instantly unwound so that the stem 17 may again be wound to wind the clock spring 16. When the coin swings the pawl 10 upwardly to release pin 14, it also swings arm 15 into the path of pin 22 on the stem 17, so that if pawl 10 remains in this position, pin 22 will prevent winding of clock. Thus it is necessary for holder 3 to be:moved 'sufliciently to move thecoin beyond projections-12 and so necessitates the deposit of the coin before .arm 15 will release pin 22. Thus it is nec- In the modification shownin Fig. 5, aver tically reciprocable slide 25 is employed in place of the pivoted pawl 10. This slide 25 has a roller .26 which will be struck by the coin so that slide will be elevated by the coin in opposition'to a spring 27. A pin or abutment 28 is arranged on the slide 25 and adapted to cooperatewith an abutment 29 on the drum 19". Another abutment on the slide 25 cooperates with a pin 31 on winding stem 17 In this way as in the previous arrangement, the spring 1'6 will bewound when the clock is wound and will be released by a coin being moved in the coin holder 3so as tostrike'slide25 and elevate the same and thereby cause abutment 28 to release pin 29 on drum 19 At the same time theabutment 30 will engage pin 31 and'hold winding stem 17 1against winding until coin holder 3 is movedsufliciently to deposit a' coin in the bank;

It will be understood that changes and modifications may be made without departing from" the spirit of the invention.

What we claim is:'

1. A clock bank having an auxiliary spring arranged'to be wound when the clock is wound, and alsohaving .ineans'to-r releasingsaid spring by a coin, and also'having means for preventing the winding operation until the coin is deposited.

2. A clock bank having an auxiliary spring arranged'to be wound when the clock is wound, and also'having means for releasing said spring'by a coin.

v3. A clock bank having an auxiliary spring mounted on the windingstemand arranged to be wound when the clock is wound so that a further winding will be prevented by said auxiliary spring, means for holding said spring in wound condition, and means whereby .a coin will release said spring to permit a further winding of the clock.

4. A clock bank having an auxiliary spring mountedon the winding stem and arranged to be wound when the clock iswound so that a further winding will be prevented by said auxiliary spring, means for holding said spring in wound condition, means whereby a coin will release said spring to permit a further winding otthe clock, and means for preventing windingof the clock evenithough said auxiliary spring is re leased, until said coin is deposited.

5. A clock bank having an auxiliary springarranged to be wound when the clock is wound so as to prevent a further wind ing of theclock, said spring being mounted on the winding spindle of the clock and having one end connected therewith, ja rotary drum in which said spring is arranged, the other end of the spring being connected with the rotary drum, a movable coin holder provided with means forholding and carrying coin, and a device interposed between the coin holder and the drum arranged to be actuated by the coin so as to release said auxiliary spring and permit the clock tobe wound.
